 Heartworm treatment to be available in limited quantities

posted October 26, 2011
 

Limited quantities of Immiticide, the only heartworm adulticide on the U.S. market, became available in October through a restricted distribution program.

The product was completely unavailable for a time because of ongoing technical issues at the U.S. plant that manufactures Immiticide for Merial. Subsequently, Merial received permission from the Food and Drug Administration to import the product from Merial's European supplier.

A Sept. 22 "dear doctor" letter from Merial states that the European supplier's production capacity will limit the amount of Immiticide available for importation to a quantity that will satisfy only a fraction of U.S. demand. According to the letter, Merial expected to receive a small shipment of the product from Europe in October and additional shipments thereafter on an intermittent basis.

The Immiticide from Europe will be available only directly from Merial through a restricted distribution program. As product becomes available, Merial will contact clinics that previously reported a need for Immiticide to treat patients with heartworm infection. Clinics that identify new cases should call (888) 637-4251, option 1.
